Minimum gelation concentration (C gel) as determined by the vial inversion test in toluene and calculated length of the PBLG α-helix (L helix), molecular weight (M n, SEC), and PDI
Sample | M n, SEC (g/mol) | PDI | L helix (nm)a | C gel (wt%) |
---|---|---|---|---|
PBLG30 | 6,500 | 1.13 | 4.5 | >2.0 |
PBLG338 | 74,000 | 1.43 | 50.7 | 0.2 |
aCalculated length of the PBLG α-helix. L helix = N PBLG × 0.15 nm, where N PBLG is the average degree of polymerization of PBLG determined by SEC–MALLS with experimentally determined dn/dc (PBLG) = 0.122 mL/g (45 °C)
